To all whom it may concern.'

Be 1t known that l, Wim-.mia Newer, a citizen of the United States otAmerica, re-

siding at Pittsburg; in the county of Allei gheny and State olPennsylvania, have mvented certain new and useful Improvements inMechanical Glass-Gatherers, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to mechanical gatherers, the primary objectbeingl to provide automatic mechanical ymeans for gathering moltenglass, and for transferring it from the furnace to the molds, la workwhich is now ordinarily performed entirely by hand.

A further object of the invention is to provide mechanism capable of'projecting a plurality of glass receiving cups into a furnncesuccessively, then lowering the cup to cause it to slightly dip into themolten glass; 'then creating a suction through the cup to fill thelatter, withdrawing the cup from the furnace and emptying its contentsirfto a mold, and finally carryii'ig the emptied cup away from the moldto make room for the next succes sive cup. i

'lhe invention comprises certain i novel combinations of devices foreffecting these several movements and operations of the cups and forinsuring a successive rotation and action thereof.

'l`he construction of the mechanism will be fully described hereinafterin connection with the aeeomininying drawings which form a. part of thisspecification and-the novel and characteristic features of the inventionwill be defined in the apj'iended claims. ln the drawings, Figure l is acentral vertical section of a machine embodying the in- 4vention` Fig.'2 is a vertical section on the line l Y-2 of Fig. l Fig, 2% is a topplan view of the revoluhle table employed in the machine, Fig. Ll is ahorizontal section on the line dwf-ll of Fig. 1, on an enlarged seele,Fig. Sis a detail perspective 'view of a portion of the main frame.`Fig. l is a detached .side elevation of the glas` hearing device, Fig. 7is a top plan view partly broken away, of the stationary frame orplatform over which the table revolves, Figs. 8 and 9 are plan views ofcams for (mcrating the reciprocating raclis of the machine, Fig. l() isa top plan view of the intermittent d riving and locking mechanism forthe revoluble table, Fig. 11 is a detail plan view of the incline on theframe for elevating certain vertically movable parts of the n1achine,Fig. 12 is a face view of one of the cams employed.

The supporting frame of the machine consists of a base 1 formed `withshaft bearings L), 3 and 4, and three platforms 5, 6 and fi arranged atdifferent elevations. The platforms 6 and 7 are each formed with a camgroove designated respectively `by the numerals S and 9.

r1 horizontal driving shaft 10 is supported in the bearings of theframe, and rising eenn tral from the upper platform is a sleeve bearing'11 within which is mounted a vertical shhft 12 to the 'upper end ofwhich is secured a circular table 1.3, seid table having a cen tralbearing 14 to receive the shaft 12, and a central cup-shaped hub 15resting upon a. 'flange 16 for-ined at the upper end of .the verticalbearing 11, la suitable Washer or wear plate 1'( being interposedbetween the hub 15 and flange 1G as shown. Upon the lower end of theVertical shaft 112 is fixed a bevel gear wheel 18 adapted to mesh with amutilated bevel gear 19 mounted upon the driving shaft 1U, saidmutilated gear having teeth on only one-third of its bearing surface inthe particular machine shown in the drewings.

Mounted upon the shaft 1() adjacent to the mutilated gear 19 andconnected therewith,

is a revolving disk 2() having a horizontal.

;tlange.21 overhanging the gear 19, and a vertically disposed frictionrim 22 adapted to' engage and' lock a revoluble cam 23 of triangular inradial lines for the greater part of their j A forni mounted upon thevertical shatt 1'2 above the bevel gear 18, the revolv- 2() having arecess 241 for the purpose' the lrevoluble tab e are arrange length,and' are then directed away from their radial courses in oppositedirections, as

Vat 28, for a purpose, tobe explainedlater on.- periphery of i operatingdevices will suffice forall, as they areall of similar construction.

Within the casing() is a revoluble sleeve 31 provided at its upper endwith a horizontally -disposed support 32 for a housing 33. Within thesleeve 31, is a hollow shaft 1134 carrying at its upper end agear wheel35, meshing with-a pinion-'Sdformed upon ythe lower end vofva revoluble`drum 37, mountedupon a vertical shaft 38-su`pported in bearings 39 and40 formed in the support 32, and the housing=33 respectively. Anothergear wheel 41 is formed upon the upper end of the drum 37, said gearwheel meshing with rack -teeth 42 formed Yupon one side ofa traveler 43extending through-the housingv and serving as a support for a tube 44,from the outer end of which is suspended a gathering cupA 45. Totheinner end of the traveler I43 is secured a hollow coupling 46 connectingthe inner end of the 'tube 44 with one end of a hose 47, l'the oppositeend of which is ccnnected to an air-cylinder 48, secured to one side ofthe casing 39 by a suitablebracket 49, as shown in Fig. 2. l

.The outer end of the tube 44 extends through a bearing 5() formed inthe housing 33, and the bearing 52 formed on the outer end of thetraveler 43.` Around the bearing is clamped a yoke 51 having -arbearing, 53 through which the tube 44 also extends. The gathering cup49 is provided with openings through which the `tube 44 extends, saidcup being thus revolubly mountedupon'the tube within the yoke 51 inposition to move over a shearing knife 54 adjustably secured to thecross-bar of the yoke by screws 53. That portion ofthe tube 44 whichextends within the "cup is formed with perforations 56 and the bottom 57of they cup is valso perforated to permit a suction of air from thecup`by the l-means shown in Fig. 2, and comprising the cylinder 48, a'piston 58 within the cylinder, v mounted upon a piston rod 59, and-aspring 60 surrounding the piston. rl.`he downward stroke of the pistonwhich sucks the air from the @up throughthe tube 44 and hose 47`is eecteby the expansion of the spring 60' after certainmeohanism which holdsthe piston against downward movement is released. The piston is providedwith a roller 614 depending below the cylinder 48 and normally restingupon a'lip 62 projecting from a sector 63 pivoted to a bracket 64secured to the frame 1 below the cylindrical casing 30. yMechanism for'coaet'ing with the sector 63 will be described hereinafter.

Within the vhollow shaft 34 is ashaft 65 upon the upper end-of which isa bevel gear `formed upon a sleeve 68 slidably keyed upon the-tube 44. i

Within the housing 33 are revolubly mounted three pairs of guide rollersbetween which the traveler 43 moves. One pair 69 of said rollers ismounted above the carrier,

posed one pair on either side of the carrier 43 below the op ositelyprojecting horizontal flanges 72 of t e carrier (Fig. 2)'.

l willnow describe the mechanism for revolving the shafts and 34.

Upon the-shaft 65 is mounted a gear 73 meshing with a horizontallydisposed rack 74, the curved inner end 75 of which carries a shortvertical shaft 87 upon the lower end of which is mounted a roller 80,adaptedtc travel in the, groove 8 of the frame 1, and from thence intothe groove 58 of a sliding ublock 89 whichtravels in the guide-ways 90of the frame 1. n the under side of the sliding block 89 is mounted asecond vertical shaft' 76 carrying a roller 77 adapted to travel in'thegroove 78 of a camvwlieel 79 mounted on and keyed to the 'shaft 10. v

Upon the lower end of the 'hollow shaft 34 are formed verticallydisposed gear teeth 3i adapted to engage -the teeth of a rack 82 similarto the rack 74, except that it is longer. The inner end of the rack 82carries a vertical shaft 83 upon the lower end of which is mounted aroller 87, adapted to travel in the groove 9 of the framel 1, and fromthence into the groove 91, of a sliding block 92, which block travels inguides 93 of the frame, said guides being similar'to the guides 90. @nthe under side of the sliding block 92 is mounted .a second verticalshaft 94 carrying a roller 84 adapted to travel in the groove 35 of acam wheel 86 mounted loosely on the shaft 10.

0n the shaft 10 is mounted and driven thereon, a sliding clutch 95having a clutch jaw 96 for the purpose of interlocking with a clutch95is mpved into or out of engagement the mechanism being so arrangedthat the clutch can only be moved Yout of engagement that is to say,before thev gathering cup 45 enters the furnace, as shown in Fig. 1.When in this position, a slot 100 formed in the cani -wheel 66 meshingwith a bevel. pinion 67,

recess inthe hub of the cam wheel'36. This f" -when the cam 86 is initsnormal position,

while the other two pairs 70 and 71 are disby a shifting lever 98carried by a bracket 99 86 is opposite the clutch lever 98, and permitssaid lever to be moved to throw the. clutch 95 out of engagement withthe cam 86,'

and the lever 98 into the slot 100, thereby releasing the cam 86 'and atthe same time locking it in its normal position. This arrangementpermits of the operation of the machine, without projecting thegathering cup into the furnace, as is sometimes necessary.

The lowering and raising of the casing 30, and the gathering cup 45 isaccomplished by n ovel mechanism which will now be described.

On the inner face 101 of the cam 79 is a rc- 'eess 102, into which dropsa roller *103, connected to the'lever 104 by a yoke 105. The lever .104is fulcrumed at the end 106 upon the bracket G4, and is connected at itsopposite end to another lever 1(17 by a sliding link 10S, said linkbeing held in position, or moved horizontally by a screw 109, carrying ahand-wheel 11i). The link 10S can move freely in a vertical direction,imlependently of the screw 10Q, which is lheld in position by bearings111 and 112 of the bracket 64.

llfhen the revoluble table is moving, al roller 113 depeni-ling fromwithin the easing 50, rolls on the surface 5 of the frame 1. At. thenormal position of the machine as shown in Fig. 1, the roller 113 hasmoved onto the lever 11)", which is adjacent to the point 114 oftheframe 1 (lfig'. 7) and forms an extension` thereof. 4

The tripping of the section 63 to create a suction in the cylinder 48,the hose 47, and the cup is accoimilished by a sector lever 115 pivotedupon the bracket 64, and con-v nected by the shaft 116 to the lever 1 17which carries on its 'end a roller 11Sv adapted to roll on theoutersurface 119 having an offset 12() which strikes and forf'es downthe roller 118.

The cup 45 isturned upside down for the purpose of emptving its contentsinto the mold by thi` roller SO being forced outward bv the offset 122in the groove 8 of the frame 1 thereby turning the shaft (55, the-shaft44 `and the cup 45.

The piston is brought back into position, andthe suction released, bythe roller (i1` rolling up lupon the incline 121, at the time that thecup 45 is turned for emptying.

".lhe teeth 81 on the shaft 34 and the teeth of the pinion 73 are longenough to permit of said cups. The initial step in the operation is toproject the cup into a furnace containing the molten glass. This iseffected through the movement of the carrier vactuated by the gears 35,36 and 41 and the rack 42. After the cup is thus projected into thefurnace it is lowered suflciently to dip into the glass the requireddistance, by the lowering of the sleeve 31 by the mechanism describedfor the purpose. The suction through the hose 47, tube 44 and cup causedby the movement of the piston within the air cylinder. 48 fills the cupwith molten glass, after which the cup is automatically turned by thegearing 66 and 67, the movement of the cup across the knife 54 servingto shear off the superfluous glass, and the cup is then raised andretracted. The revolving movement of the table then 'carries the cup tothe mold where it is emptied. The several cups employed are thussuccessively operated.

An important feature of' the improvement, is that bythe construction ofthe guide grooves 25, 26 and 27, the cup carriers are directed todifferent points within the furnace so that each successive cup will dipinto a ditieri-ait'part of the molten glass.

The actuating mechanism is so constructed that the table 13 will bestationary while the cups are being projected, and the cams employed areso timed as to cause an intermittent successive voperation of thedifferent sets of cup-operating mechanism.

l would have it understood that the invention is notre'strieted to theexact construction of mechanism shown and described, as variousmmlitications in the construction and relative arrangement of the partsof the mechanism may be resorted to without departing from the spirit ofthe invention, and the scope of the following claims.
